Subject: Re: 2.6.22.14 oops msg with commvault galaxy ?

Hi Vincent,

Could you please see if the following patch removes the oops due to CFS
sysfs files? (There might still be the other oops due to the floppy
sysfs files)

Ingo, could you please add this patch in your CFS backport to 2.6.22 and
older kernels?

Thanks,

kdump showed that the owner field had some junk value which caused
the oops reported at http://lkml.org/lkml/2007/12/10/113 . This
patch sets the value of that field to NULL.
